Abstract  Twenty-four white clover (Trifolium repens) breeding lines from a single cycle of selection for extremes of leaf size, internode length, and proportion of nodes branching in both full sunlight and 50% sunlight (shade) were compared with six cultivars over 3 years. These comparisons were conducted in New Zealand at a flat fertile lowland site rotationally grazed by sheep, and a steep hill country lower fertility site rotationally grazed by sheep and cattle. Selection for extremes of leaf size had the most consistent effect on clover content and yield.

Keywords  white clover; stolon; branching; internode length; persistence; yield; adaptation
